var json = '{"glossary":{"title":"example glossary","GlossDiv":{"title":"S","GlossList":{"GlossEntry":{"ID":"SGML","SortAs":"SGML","GlossTerm":"Standard Generalized Markup Language","Acronym":"SGML","Abbrev":"ISO 8879:1986","GlossDef":{"para":"A meta-markup language, used to create markup languages such as DocBook.","ID":"44","str":"SGML","GlossSeeAlso":["GML","XML"]},"GlossSee":"markup"}}}}}';

var js = JSON.parse(json);

//example of grabbing objects that match some key and value in JSON
console.log(getObjects(js,'ID','SGML'));
//returns 1 object where a key names ID has the value SGML

//example of grabbing objects that match some key in JSON
console.log(getObjects(js,'ID',''));
//returns 2 objects since keys with name ID are found in 2 objects

//example of grabbing obejcts that match some value in JSON
console.log(getObjects(js,'','SGML'));
//returns 2 object since 2 obects have keys with the value SGML

//example of grabbing objects that match some key in JSON
console.log(getObjects(js,'ID',''));
//returns 2 objects since keys with name ID are found in 2 objects

//example of grabbing values from any key passed in JSON
console.log(getValues(js,'ID'));
//returns array ["SGML", "44"] 

//example of grabbing keys by searching via values in JSON
console.log(getKeys(js,'SGML'));
//returns array ["ID", "SortAs", "Acronym", "str"] 

Or are you trying to search on the key? In that case you could just specify the needle as *? Is that what you're looking for? If you could provide more details with expected output I'd be able to help better

yeah i try to search at the key so i should use * instead of ** ? ah yeah is it work on ReactJs too ?

@mzcoder-hub I'd really recommend you take a look at the readme here . It details all the basic use cases and it sound like yours is one of them. Your question is not very clear and so I can't answer it. So you have to options:

1. go to the readme and figure out what you need to know yourself
2. reformulate the question in a way that I can understand (ideally with example results!) and I will do my best to provide a working solution

Thank you, L~

@simlu i have this data https://prnt.sc/115tz4e and the key is not fixed its generate from database, and i want to search keyword example "merah" and i want to retrieve data from array "merah"

Is this what you want?

const objectScan = require('object-scan');

const data = { merah: [{ harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49' }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98' }], hijau: [{ harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }] };

console.log(objectScan(['*[*]'])(data));
// => [ [ 'hijau', 1 ], [ 'hijau', 0 ], [ 'merah', 1 ], [ 'merah', 0 ] ]

Is this what you want?

const objectScan = require('object-scan');

const data = { merah: [{ harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49' }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98' }], hijau: [{ harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }] };

console.log(objectScan(['*[*]'])(data));
// => [ [ 'hijau', 1 ], [ 'hijau', 0 ], [ 'merah', 1 ], [ 'merah', 0 ] ]

i want to get data inside of array object

[
    {
      harga: 30000,
      sku: 'SKU-123asd-asdasd',
      stok: '20',
      ukuran: 'XL',
      warna: 'Merah',
      _id: '6069895a0e277a332ca19e49',
    },
    {
      harga: 30000,
      sku: 'SKU-123asd-asdasda',
      stok: '20',
      ukuran: 'L',
      warna: 'Merah',
      _id: '606b6ea7ff4a142508df2a98',
    },
  ],

only single key

if i search 'merah' i only get data from array object from key 'merah'

Still guessing what you want... how about this?

const objectScan = require('object-scan');

const data = { merah: [{ harga: 30000, sku: 'SKU-123asd-asdasd', stok: '20', ukuran: 'XL', warna: 'Merah', _id: '6069895a0e277a332ca19e49' }, { harga: 30000, sku: 'SKU-123asd-asdasda', stok: '20', ukuran: 'L', warna: 'Merah', _id: '606b6ea7ff4a142508df2a98' }], hijau: [{ harga: 30000, sku: 'SKU-123asd-asdasds', stok: '20', ukuran: 'XL', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }, { harga: 30000, sku: 'SKU-123asd-asdasdsa', stok: '20', ukuran: 'L', warna: 'Hijau', _id: '606b6ea7ff4a142508df2a98' }] };

const r = objectScan(['*[*]'], { rtn: 'value' })(data);
console.log(JSON.stringify(r));
// => [{"harga":30000,"sku":"SKU-123asd-asdasdsa","stok":"20","ukuran":"L","warna":"Hijau","_id":"606b6ea7ff4a142508df2a98"},{"harga":30000,"sku":"SKU-123asd-asdasds","stok":"20","ukuran":"XL","warna":"Hijau","_id":"606b6ea7ff4a142508df2a98"},{"harga":30000,"sku":"SKU-123asd-asdasda","stok":"20","ukuran":"L","warna":"Merah","_id":"606b6ea7ff4a142508df2a98"},{"harga":30000,"sku":"SKU-123asd-asdasd","stok":"20","ukuran":"XL","warna":"Merah","_id":"6069895a0e277a332ca19e49"}]

Im fixing it using the script above

console.log(getObjects(js,'','SGML'));

@YagoLopez Thanks! Exactly what I need and it works great
